Thank you very much indeed BAV, sorry i didnot mean to be cheap, as i do understand business needs some backup and foundation. but as I am new to this business, so had some doubts, both esignal and Qcharts provides advance charting facilities and esignal provides backtesting and other indicators and RTsignals. After seeing their features i will surely go for either of them as Odin etc data stands no where, thanks for your help but i was confused becoz after reading the reviews on elitetrader and other blogs I was thinking they are really expensive but maybe in india we dont have good vendors who can match their quality like in the UK many good broker provides good datafeeds plus basic charting tool for like 20-40pounds/month like sharescope but not for Indian markets I think.
